3 Potato 4 also offers Aztec chili, chipotle-sweet potato soup, frozen vegan chocolate-dipped bananas called Banana Rockets, Zevia sodas, coconut water, kombucha and other vegan drinks. The Salem, Mass.-based franchise uses only biodegradable or recyclable packaging. According to the company’s website, the goal of 3 Potato 4 is to “reintroduce the potato for its merits as an antioxidant, a mega-doser of vitamin A, [with] more potassium than a banana and 37 percent of your daily vitamin C.”
